Design and development
The aircraft was designed long before the adoption of the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of 254 lb (115 kg), but nonetheless complies with them. The aircraft has a standard empty weight of 150 lb (68 kg) and is billed as the "World's Tiniest Homebuilt Helicopter" by the plans supplier. It features a single main rotor and tail rotor, a single-seat open cockpit without a windshield, tricycle landing gear with main wheels and nose skid and a twin cylinder, air-cooled, two-stroke, single-ignition 40 hp (30 kW) Rotax 447 aircraft engine or Kawasaki 440 snowmobile engine. The 50 hp (37 kW) Rotax 503 can also be used.
The aircraft fuselage is made from bolted-together aluminum tubing. Its main rotor is 12 ft (3.7 m) in diameter. Fuel capacity is 5 U.S. gallons (19 L; 4.2 imp gal).
